An apparatus for constructing driven filling pile is composed of a driver, a holder and a hollow steel pipe as tool. A technology for constructing a pile includes such steps as driving the hollow steel pile held by said holder in earth, filling concrete in the hole generated by said steel pile, further driving steel pile and filling concrete until needed depth, pulling up said steel pile, and solidifying concrete pile underground. Its advantages are high load bearing power and side friction force, high speed, and no need of sludge. |
